I recently bought a patch and can’t find anything about it, I asked the seller and they said it was in a bulk set of patches and that they know nothing about it, I tried doing research but I still didn’t find anything about it, if anyone can help me I would be in debt to you the rest of my life

The bio of the patch just says “SI GROUP DTS SUA SPONTE Patch 81E5”
